One end of the movable body 7 is a convex portion 71, and the other end of the movable body 7 is an inclined surface 73 inclined with respect to the axial direction of the tube 3.SELECTED DRAWING: Figure 1

Description

本発明は、スプリングコネクタに関する。 The present invention relates to a spring connector.

図９は、従来のスプリングコネクタ１００の構成例を示す図であり、チューブ３０を切り欠いて内部の構造を示した縦断面図である。図９に示すように、スプリングコネクタ１００は、チューブ３０の開口する一端側から突出する可動ピン５０を備える。可動ピン５０は、チューブ３０内のスプリング８０によって突出方向に付勢される。 FIG. 9 is a diagram showing a configuration example of the conventional spring connector 100, and is a vertical cross-sectional view showing the internal structure of the tube 30 by cutting out the tube 30. As shown in FIG. 9, the spring connector 100 includes a movable pin 50 projecting from one end side of the opening of the tube 30. The movable pin 50 is urged in the protruding direction by the spring 80 in the tube 30.

可動ピンには様々な先端形状のものがあり、接触対象の形状に適した先端形状のものを選択することができる。例えば、図９に示すように先端部５０１が半球形状のものを選択することができる。また、可動ピン５０の後端部は、チューブ３０の軸方向に対して傾斜した傾斜面５０３をなす。したがって、使用時に可動ピン５０の先端部５０１を接触対象９０に接触させて可動ピン５０をチューブ３０に押し込むと、スプリング８０の反力が傾斜面５０３に加えられて、チューブ３０の軸方向に対して垂直方向の力が可動ピン５０に作用する。すると、可動ピン５０の側面の一部分がチューブ３０の内壁に押し付けられる（矢印Ａ１１）。また、接触対象９０の接触面が平面であることから、接触対象９０の接触面上で先端部５０１が転動することで可動ピン５０の中心軸が傾いて（矢印Ａ１３）、可動ピン５０の側面の他の部分がチューブ３０の内壁に押し付けられる（矢印Ａ１５）。これにより、可動ピン５０とチューブ３０との接触・導通が確保される。 There are various tip shapes for the movable pin, and a tip shape suitable for the shape of the contact target can be selected. For example, as shown in FIG. 9, a hemispherical tip portion 501 can be selected. Further, the rear end portion of the movable pin 50 forms an inclined surface 503 inclined with respect to the axial direction of the tube 30. Therefore, when the tip portion 501 of the movable pin 50 is brought into contact with the contact target 90 and the movable pin 50 is pushed into the tube 30 during use, the reaction force of the spring 80 is applied to the inclined surface 503 and with respect to the axial direction of the tube 30. A vertical force acts on the movable pin 50. Then, a part of the side surface of the movable pin 50 is pressed against the inner wall of the tube 30 (arrow A11). Further, since the contact surface of the contact target 90 is flat, the central axis of the movable pin 50 is tilted by rolling the tip portion 501 on the contact surface of the contact target 90 (arrow A13), and the movable pin 50 The other part of the side surface is pressed against the inner wall of the tube 30 (arrow A15). As a result, contact / continuity between the movable pin 50 and the tube 30 is ensured.

また、特許文献１では、チューブ開口部の穴の偏芯により押し込み時に可動ピンが傾くようにし、可動ピンの後端部を円錐状面にすることで導通を取るようにしている。 Further, in Patent Document 1, the movable pin is tilted at the time of pushing due to the eccentricity of the hole of the tube opening, and the rear end portion of the movable pin is made into a conical surface to provide continuity.

一方で、接触対象の表面に形成された被膜の除去等を目的として先端部に複数の突起を設け、先端形状を突端形状とした可動ピンが知られている。図１０は、図９の可動ピン５０を先端部５０１ａが突端形状の可動ピン５０ａに置き換えたスプリングコネクタ１００ａを示す縦断面図である。本構成では、使用時に先端部５０１ａの各突起が接触対象９０と当接する。図１０の可動ピン５０ａによれば、先端部５０１ａの各突起は、突起先端を結ぶと仮想的な平面が規定できる位置関係にある。 On the other hand, there is known a movable pin in which a plurality of protrusions are provided at the tip portion and the tip shape is a tip shape for the purpose of removing a coating film formed on the surface of a contact target. FIG. 10 is a vertical cross-sectional view showing a spring connector 100a in which the movable pin 50 of FIG. 9 is replaced with a movable pin 50a having a tip portion 501a having a tip shape. In this configuration, each protrusion of the tip portion 501a comes into contact with the contact target 90 during use. According to the movable pin 50a of FIG. 10, each protrusion of the tip portion 501a has a positional relationship in which a virtual plane can be defined by connecting the tip of the protrusion.

図１０に示した従来のスプリングコネクタでは、可動ピン５０ａの先端部５０１ａが接触対象９０の接触面に接触すると、可動ピン５０ａは、その中心軸がチューブ３０の中心軸に沿った状態となり、その状態を保ったままチューブ３０に押し込まれる。そのため、チューブ３０と可動ピン５０ａとの接触が不安定となり、チューブ３０と可動ピン５０ａとの間の電流の通電量低下に伴うチューブ３０と可動ピン５０ａとの間の接触抵抗の増加や、スプリング８０を介した電流の通電量増加に伴うスプリング８０の焼損、等を招くおそれがあり、スプリングコネクタが劣化するおそれがある。 In the conventional spring connector shown in FIG. 10, when the tip portion 501a of the movable pin 50a comes into contact with the contact surface of the contact target 90, the movable pin 50a is in a state where its central axis is along the central axis of the tube 30. It is pushed into the tube 30 while maintaining the state. Therefore, the contact between the tube 30 and the movable pin 50a becomes unstable, and the contact resistance between the tube 30 and the movable pin 50a increases as the amount of current applied between the tube 30 and the movable pin 50a decreases, and the spring The spring 80 may be burnt due to an increase in the amount of current energized through the 80, and the spring connector may be deteriorated.

そこで本発明の目的の一例は、可動ピンの先端形状に関わらず、スプリングコネクタにおける接触安定性の向上を図ることができる技術を提供することである。 Therefore, an example of an object of the present invention is to provide a technique capable of improving contact stability in a spring connector regardless of the shape of the tip of a movable pin.

本発明の第１の態様は、導電性のチューブと、前記チューブの軸方向に沿って前記チューブの開口から先端部が突出する可動ピンと、前記チューブ内に設けられ、一端部が前記可動ピンの後端部と接触する可動体と、前記チューブ内に設けられ、前記可動体の他端部を前記可動ピンの突出する方向に付勢するスプリングと、を備え、前記可動体の他端部は、前記軸方向に対して傾斜した傾斜面であり、前記可動体の一端部、および、前記可動ピンの後端部、の少なくとも一方は、凸部を有する、スプリングコネクタである。 A first aspect of the present invention is a conductive tube, a movable pin having a tip protruding from an opening of the tube along the axial direction of the tube, and a movable pin provided in the tube, one end of which is the movable pin. A movable body that comes into contact with the rear end portion and a spring that is provided in the tube and urges the other end portion of the movable body in the direction in which the movable pin protrudes are provided, and the other end portion of the movable body is provided. , An inclined surface inclined with respect to the axial direction, and at least one end of the movable body and the rear end of the movable pin is a spring connector having a convex portion.

この第１の態様によれば、可動ピンとスプリングとの間に可動体を介在させてその一端部を可動ピンの後端部と接触させるとともに、スプリングによって可動体の他端部を可動ピンの突出する方向（突出方向）に付勢する。そして、可動体の他端部をチューブの軸方向に対して傾斜した傾斜面とし、可動体の一端部および可動ピンの後端部のうちの少なくとも一方を凸部を有する構成とする。これによれば、可動体がチューブ内で傾き、その側面がチューブの内壁に押し付けられる。よって、使用時において可動体とチューブとを確実に接触させることができ、可動体を介して可動ピンとチューブとの間の安定した電気的接続が実現できる。したがって、可動ピンの先端形状に関わらず、スプリングコネクタにおける接触安定性の向上を図ることができる技術を提供できる。 According to this first aspect, a movable body is interposed between the movable pin and the spring so that one end thereof is brought into contact with the rear end portion of the movable pin, and the other end of the movable body is projected by the spring. Bias in the direction of spring (protruding direction). The other end of the movable body is an inclined surface inclined with respect to the axial direction of the tube, and at least one of one end of the movable body and the rear end of the movable pin is configured to have a convex portion. According to this, the movable body is tilted in the tube, and its side surface is pressed against the inner wall of the tube. Therefore, the movable body and the tube can be surely brought into contact with each other during use, and a stable electrical connection between the movable pin and the tube can be realized via the movable body. Therefore, regardless of the tip shape of the movable pin, it is possible to provide a technique capable of improving the contact stability of the spring connector.

以下、図面を参照して、本発明の好適な実施形態について説明する。なお、以下説明する実施形態によって本発明が限定されるものではなく、本発明を適用可能な形態が以下の実施形態に限定されるものでもない。また、図面の記載において、同一部分には同一の符号を付す。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. It should be noted that the embodiments described below do not limit the present invention, and the embodiments to which the present invention can be applied are not limited to the following embodiments. Further, in the description of the drawings, the same parts are designated by the same reference numerals.

図１および図２は、本実施形態におけるスプリングコネクタ１０の構成例を示す縦断面図であり、図１は、可動ピン５が突出した状態を示し、図２は、可動ピン５の先端部５１１が押されてチューブ３内に後退した状態を示している。図１および図２に示すように、スプリングコネクタ１０は、一端が開口したチューブ３と、チューブ３の軸方向に沿ってチューブ３の開口から先端部５１１が突出する可動ピン５と、チューブ３内に設けられて一端が可動ピン５の後端部と接触する可動体７と、チューブ３内に設けられて可動体７の他端部を可動ピン５の突出する方向（突出方向）に付勢するスプリング８と、を備える。 1 and 2 are vertical cross-sectional views showing a configuration example of the spring connector 10 in the present embodiment, FIG. 1 shows a state in which the movable pin 5 protrudes, and FIG. 2 shows a tip portion 511 of the movable pin 5. Is pushed and retracted into the tube 3. As shown in FIGS. 1 and 2, the spring connector 10 includes a tube 3 having one end opened, a movable pin 5 having a tip portion 511 protruding from the opening of the tube 3 along the axial direction of the tube 3, and the inside of the tube 3. The movable body 7 provided in the tube 3 and one end of which contacts the rear end of the movable pin 5 and the other end of the movable body 7 provided in the tube 3 are urged in the protruding direction (protruding direction) of the movable pin 5. The spring 8 and the spring 8 are provided.

チューブ３は、導電性の材料（例えば、銅又は銅合金等）により作られた筒状体であり、開口する一端側において可動ピン５を軸方向に摺動可能に保持する。チューブ３の開口端は、かしめ加工によって内側に曲げられて係止部３１とされており、可動ピン５の抜けを防止する。 The tube 3 is a tubular body made of a conductive material (for example, copper or a copper alloy), and holds the movable pin 5 so as to be slidable in the axial direction on one end side of the opening. The open end of the tube 3 is bent inward by caulking to form a locking portion 31, which prevents the movable pin 5 from coming off.

可動ピン５は、導電性の材料（例えば、銅又は銅合金等）により作られる。この可動ピン５は、小径部５１と、それより大径の大径部５３とで構成され、小径部５１の先端である先端部５１１が、接触対象９（図２を参照）である端子と接触する接触部となる。小径部５１と大径部５３とは有段で繋がっており、両者の間のテーパー状の段差面５５がチューブ３の係止部３１と当接して、可動ピン５がチューブ３から抜けるのを防ぐ構成となっている。したがって、大径部５３は、小径部５１がチューブ３から突出した状態であってもチューブ３内に位置する。 The movable pin 5 is made of a conductive material (eg, copper or copper alloy, etc.). The movable pin 5 is composed of a small diameter portion 51 and a large diameter portion 53 having a larger diameter, and the tip portion 511, which is the tip of the small diameter portion 51, is a terminal that is a contact target 9 (see FIG. 2). It becomes a contact part that comes into contact. The small diameter portion 51 and the large diameter portion 53 are connected in a stepped manner, and the tapered stepped surface 55 between the two is in contact with the locking portion 31 of the tube 3 to prevent the movable pin 5 from coming out of the tube 3. It is configured to prevent. Therefore, the large diameter portion 53 is located in the tube 3 even when the small diameter portion 51 protrudes from the tube 3.

本実施形態では、この可動ピン５の後端部である大径部５３の後端は、平坦な平面部５３１とされる。 In the present embodiment, the rear end of the large diameter portion 53, which is the rear end of the movable pin 5, is a flat flat surface portion 531.

一方、可動ピン５の先端部５１１は、接触対象９に対して面接触する仮想的なコンタクト面ＶＦを構成する突端形状を有する。図３は、可動ピン５の先端部５１１の突端形状を拡大して示す斜視図である。本実施形態では、図３に示すように、先端部５１１は、４つの突起による突端形状とされる。したがって、図１および図２に示すように、各突起の頂点によって定まる面が、接触対象９と面接触するコンタクト面ＶＦとなる。 On the other hand, the tip portion 511 of the movable pin 5 has a tip shape that constitutes a virtual contact surface VF that makes surface contact with the contact target 9. FIG. 3 is an enlarged perspective view showing the shape of the tip of the tip portion 511 of the movable pin 5. In the present embodiment, as shown in FIG. 3, the tip portion 511 has a tip shape with four protrusions. Therefore, as shown in FIGS. 1 and 2, the surface determined by the vertices of each protrusion is the contact surface VF that makes surface contact with the contact target 9.

なお、可動ピン５の先端形状を突端形状とする場合の当該形状は図３に示す４つの突起に限定されるものではなく、コンタクト面を構成できればよい。先端部に突起を設けるのであれば、突起の数は２つや３つとしてもよいし、５以上としてもよい。例えば、図４に示す先端部５１１ａのように、多数の突起を有する突端形状としてもよい。 When the tip shape of the movable pin 5 is a tip shape, the shape is not limited to the four protrusions shown in FIG. 3, and it is sufficient that the contact surface can be formed. If the protrusions are provided at the tip, the number of protrusions may be two, three, or five or more. For example, as in the tip portion 511a shown in FIG. 4, a tip shape having a large number of protrusions may be used.

また、先端部の突端形状は、ライン状のエッジとすることもできる。例えば、図５に示すように、可動ピンの先端部５１１ｂを、その突出方向の反対方向（後退方向）に凸となる円錐形状や湾曲形状（図示せず）を凹部として有し、その凹部の縁部をエッジ５１３として設けた構成としてもよい。 Further, the tip shape of the tip portion may be a line-shaped edge. For example, as shown in FIG. 5, the tip portion 511b of the movable pin has a conical shape or a curved shape (not shown) that is convex in the direction opposite to the protruding direction (backward direction) as a concave portion, and the concave portion has a concave shape. The edge portion may be provided as an edge 513.

可動体７は、導電性の材料（例えば、銅又は銅合金等）により作られる。この可動体７は、可動ピン５の後端部と接触する側の一端部が凸部７１をなす。凸部７１は、例えば、図１に示す弓形回転体形状等の湾曲形状とすることができる。その他、凸部７１の湾曲形状は、円錐形状等としてもよい。一方、可動体７のスプリング８と接触する側の他端部は、チューブ３の軸方向に対して傾斜した傾斜面７３をなす。 The movable body 7 is made of a conductive material (for example, copper or a copper alloy). The movable body 7 has a convex portion 71 at one end on the side that contacts the rear end of the movable pin 5. The convex portion 71 may have a curved shape such as the arcuate rotating body shape shown in FIG. 1, for example. In addition, the curved shape of the convex portion 71 may be a conical shape or the like. On the other hand, the other end of the movable body 7 on the side in contact with the spring 8 forms an inclined surface 73 inclined with respect to the axial direction of the tube 3.

スプリング８は、例えば、ピアノ線やステンレス線材により作ることができるコイルスプリングである。或いは、スプリング８は、絶縁材で作られていてもよいし、絶縁被膜で被覆されたものでもよい。 The spring 8 is, for example, a coil spring that can be made of a piano wire or a stainless steel wire. Alternatively, the spring 8 may be made of an insulating material or may be coated with an insulating coating.

当該構成によって、可動体７とチューブ３との接触・導通が確保される。先ず、本構成では、使用時に接触対象９が先端部５１１に押し付けられると、図２に示すように、先端部５１１の各突起が接触対象９と当接し、先端部５１１が接触対象９とコンタクト面ＶＦで面接触する。 With this configuration, contact / continuity between the movable body 7 and the tube 3 is ensured. First, in this configuration, when the contact target 9 is pressed against the tip portion 511 during use, each protrusion of the tip portion 511 comes into contact with the contact target 9, and the tip portion 511 contacts the contact target 9. Surface contact with surface VF.

ここで、可動ピン５は、その中心軸がチューブ３の軸方向に沿う向きでチューブ３に挿入されている。よって、コンタクト面ＶＦは、その法線方向がチューブ３の軸方向に沿った方向となる。したがって、可動ピン５は、その中心軸がチューブ３の中心軸に沿った状態を保ったままチューブ３に押し込まれる。 Here, the movable pin 5 is inserted into the tube 3 with its central axis oriented along the axial direction of the tube 3. Therefore, the normal direction of the contact surface VF is the direction along the axial direction of the tube 3. Therefore, the movable pin 5 is pushed into the tube 3 while keeping its central axis along the central axis of the tube 3.

そして、可動ピン５がチューブ３に押し込まれたことで発生するスプリング８の反力は可動体７の他端部である傾斜面７３に加えられ、チューブ３の軸方向に対して垂直方向の力が可動ピン５に作用する。すると、可動体７の側面の一部分がチューブ３の内壁に押し付けられ（矢印Ａ１）、可動ピン５の後端部である平面部５３１上で可動体７の一端部である凸部７１が転動し（矢印Ａ２）、可動体７の側面の他の部分がチューブ３の内壁に押し付けられる（矢印Ａ３）。これにより、可動体７とチューブ３との接触・導通が確保される。可動体７は可動ピン５と確実に接触している。このため、接触対象９とチューブ３との間の導通を確実に確保することができる。 Then, the reaction force of the spring 8 generated when the movable pin 5 is pushed into the tube 3 is applied to the inclined surface 73 which is the other end of the movable body 7, and the force in the direction perpendicular to the axial direction of the tube 3 is applied. Acts on the movable pin 5. Then, a part of the side surface of the movable body 7 is pressed against the inner wall of the tube 3 (arrow A1), and the convex portion 71, which is one end of the movable body 7, rolls on the flat surface portion 531 which is the rear end portion of the movable pin 5. (Arrow A2), the other part of the side surface of the movable body 7 is pressed against the inner wall of the tube 3 (arrow A3). As a result, contact / continuity between the movable body 7 and the tube 3 is ensured. The movable body 7 is in reliable contact with the movable pin 5. Therefore, the continuity between the contact target 9 and the tube 3 can be reliably ensured.

したがって、本実施形態によれば、先端形状を突端形状としたことで可動ピン５とチューブ３との接触が不十分となったとしても、可動ピン５の後端部（平面部５３１）と接触する可動体７をチューブ３と確実に接触させることができ、可動体７を介して可動ピン５とチューブ３との間の安定した電気的接続が実現できる。したがって、可動ピンの先端形状に関わらず、スプリングコネクタ１０における接触安定性の向上を図ることができる技術を提供できる。またその結果、可動ピンの先端形状の設計自由度が向上する。加えて、接触対象の表面に形成された酸化被膜の貫通性を向上させることが可能となる。 Therefore, according to the present embodiment, even if the contact between the movable pin 5 and the tube 3 is insufficient due to the tip shape being the tip shape, the contact with the rear end portion (flat surface portion 531) of the movable pin 5 is reached. The movable body 7 can be reliably brought into contact with the tube 3, and a stable electrical connection between the movable pin 5 and the tube 3 can be realized via the movable body 7. Therefore, regardless of the tip shape of the movable pin, it is possible to provide a technique capable of improving the contact stability of the spring connector 10. As a result, the degree of freedom in designing the tip shape of the movable pin is improved. In addition, it is possible to improve the penetrability of the oxide film formed on the surface of the contact target.

なお、上記実施形態では、チューブ３の一端側に可動ピン５が設けられたスプリングコネクタ１０を例示したが、チューブの両端側に可動ピンが設けられた構成のスプリングコネクタにも本実施形態を同様に適用できる。 In the above embodiment, the spring connector 10 in which the movable pins 5 are provided on one end side of the tube 3 is illustrated, but the same embodiment applies to the spring connector having the movable pins provided on both ends of the tube. Can be applied to.

また、上記実施形態では、可動ピン５の後端部を平面部５３１とし、この平面部５３１と接触する一端部を凸部７１とした可動体７を例示したが、可動ピンの後端部を凸部としてもよい。図６は、変形例におけるスプリングコネクタ１０ａの構成例を示す縦断面図であり、図７は、他の変形例におけるスプリングコネクタ１０ｂの構成例を示す縦断面図である。 Further, in the above embodiment, the movable body 7 in which the rear end portion of the movable pin 5 is a flat surface portion 531 and one end portion in contact with the flat surface portion 531 is a convex portion 71 is illustrated. It may be a convex part. FIG. 6 is a vertical cross-sectional view showing a configuration example of the spring connector 10a in the modified example, and FIG. 7 is a vertical cross-sectional view showing a configuration example of the spring connector 10b in another modified example.

例えば、図６に示すように、可動ピン５ａの後端部である大径部５３ａの後端を凸部５３３ａとし、可動体７ａの一端部を平坦な平面部７２ａとしてスプリングコネクタ１０ａを構成してもよい。本構成によっても、上記実施形態と同様の効果を奏することができる。 For example, as shown in FIG. 6, the spring connector 10a is configured by using the rear end of the large diameter portion 53a, which is the rear end of the movable pin 5a, as the convex portion 533a and one end of the movable body 7a as the flat flat surface portion 72a. You may. Even with this configuration, the same effect as that of the above embodiment can be obtained.

また、図７に示すように、可動ピン５ｂの後端部である大径部５３ｂの後端を凸部５３３ｂとする一方、可動体７ｂの両端部を、チューブ３の軸方向に対して傾斜した傾斜面７２ｂ，７３ｂとしてスプリングコネクタ１０ｂを構成してもよい。より詳細には、図７では可動体７ｂを側面視が台形形状の対称形状とすることで、可動ピン５ｂの後端部と接触する一端部とスプリング８によって付勢される他端部の両方を傾斜面７２ｂ，７３ｂとする。本構成では、可動体７ｂの傾きは発生しないものの、図７中の各矢印で示すように、可動体７ｂがチューブ３の一方の側面に押し付けられて、可動体７ｂとチューブ３との接触・導通が確保される。したがって、可動ピン５ｂの後端部（凸部５３３ｂ）と接触する可動体７ｂをチューブ３と確実に接触させることができ、上記実施形態と同様の効果を奏することができる。また、可動体７ｂの一端部および他端部の両方が傾斜面であるので、製造時にチューブ３に可動体７ｂを挿入する際、その向きを意識する必要がなくなる。図７では、可動体７ｂの一端部および他端部の両方傾斜面を非平行とした側面視が台形形状の対称形状としたが、一端部および他端部の両方傾斜面を平行とした側面視が平行四辺形形状の可動体を採用してもよい。 Further, as shown in FIG. 7, the rear end of the large diameter portion 53b, which is the rear end of the movable pin 5b, is a convex portion 533b, while both ends of the movable body 7b are inclined with respect to the axial direction of the tube 3. The spring connector 10b may be configured as the inclined surfaces 72b and 73b. More specifically, in FIG. 7, the movable body 7b has a trapezoidal symmetrical shape in the side view, so that both one end portion in contact with the rear end portion of the movable pin 5b and the other end portion urged by the spring 8 are formed. Let the inclined surfaces 72b and 73b. In this configuration, although the movable body 7b is not tilted, the movable body 7b is pressed against one side surface of the tube 3 as shown by each arrow in FIG. 7, and the movable body 7b and the tube 3 come into contact with each other. Continuity is ensured. Therefore, the movable body 7b that comes into contact with the rear end portion (convex portion 533b) of the movable pin 5b can be surely brought into contact with the tube 3, and the same effect as that of the above embodiment can be obtained. Further, since both one end and the other end of the movable body 7b are inclined surfaces, it is not necessary to be aware of the orientation when inserting the movable body 7b into the tube 3 at the time of manufacturing. In FIG. 7, the side view in which both the inclined surfaces of one end and the other end of the movable body 7b are non-parallel is a trapezoidal symmetrical shape, but the side surface in which both the inclined surfaces of one end and the other end are parallel. A movable body having a parallelogram shape may be adopted.

あるいは、図示しないが、可動ピンの後端部と、可動体の一端部の両方を凸部としてスプリングコネクタを構成してもよい。 Alternatively, although not shown, the spring connector may be configured with both the rear end portion of the movable pin and one end portion of the movable body as convex portions.

また、上記実施形態では、可動ピンの先端部の形状として複数の突起を有する突端形状を例示したが、他の形状のものにも適用が可能である。図８は、変形例に係るスプリングコネクタ１０ｃの構成例を示す縦断面図である。本変形例のスプリングコネクタ１０ｃでは、可動ピン５ｃの先端部５１１ｃ（小径部５１ｃの先端）の形状を半球形状としている。また、図８のように、接触対象９ｃの接触面は、円錐形状や湾曲形状等の窪んだ凹状である。この場合には、使用時に接触対象９ｃが可動ピン５ｃに押し付けられるとその半球形状の先端部５１１ｃが窪みに嵌り、可動ピン５ｃの中心軸がチューブ３の中心軸に沿った状態を保ったままチューブ３に押し込まれる。よって、上記実施形態で説明したのと同様に矢印Ａ１〜Ａ３で示すように可動体７が動いて、可動体７とチューブ３との接触・導通が確保される。したがって、上記実施形態と同様の効果を奏することができる。 Further, in the above embodiment, the shape of the tip of the movable pin is illustrated as a tip shape having a plurality of protrusions, but it can be applied to other shapes. FIG. 8 is a vertical cross-sectional view showing a configuration example of the spring connector 10c according to the modified example. In the spring connector 10c of this modified example, the shape of the tip portion 511c (tip of the small diameter portion 51c) of the movable pin 5c is a hemispherical shape. Further, as shown in FIG. 8, the contact surface of the contact target 9c has a concave shape such as a conical shape or a curved shape. In this case, when the contact target 9c is pressed against the movable pin 5c during use, the hemispherical tip portion 511c fits into the recess, and the central axis of the movable pin 5c remains along the central axis of the tube 3. It is pushed into the tube 3. Therefore, the movable body 7 moves as shown by arrows A1 to A3 in the same manner as described in the above embodiment, and the contact / continuity between the movable body 7 and the tube 3 is ensured. Therefore, the same effect as that of the above embodiment can be obtained.
